Advanced computer systems and passenger features might stop a bit short of the artificial intelligence we've been promised by the tech utopians, but they're real and available (though they're not cheap). From cars that steer themselves to brakes that adjust for individual drivers, here's a look at some of the most high-tech vehicles you can drive in—or that might be passing or tailgating your car already.
